Abstract

The invention discloses a light foaming TPU shoe sole which comprises a TPU shoe sole base body, a foam pad adheres to the top end of the TPU shoe sole base body, a plurality of cavities are formed inthe bottom end of the foam pad, an adhesive layer adheres to the edge of the foam pad, a resin layer adheres to the front end of the foam pad in an embedded mode, and an insole layer adheres to the top end of the foam pad. A damping cavity is formed in the heel position of the TPU shoe sole base body, the damping cavity is filled with elastic cotton, and a plurality of TPU foaming particles are embedded in the sole position of the TPU shoe sole base body. The structure is scientific and reasonable, safe and convenient use, normal sole contact can be facilitated through the foam pad; the hardeffect of the front end of the shoe sole can be improved through the resin layer, the toes are protected and prevented from being injured by collision, and the vibration feeling generated when the shoe sole makes contact with the ground in the walking process can be improved through mutual cooperation of the cavity, the damping cavity and the elastic cotton.

Description

technical field [0001] The invention relates to the technical field of TPU shoe soles, in particular to a lightweight foamed TPU shoe sole and a manufacturing process thereof. Background technique [0002] The name of TPU is thermoplastic polyurethane elastomer rubber, which is mainly divided into polyester type and polyether type. It has a wide range of hardness (60HA-85HD), wear resistance, oil resistance, transparency, and good elasticity. It is widely used in daily necessities, sporting goods, toys, and decorative materials. Halogen-free flame-retardant TPU can also replace soft PVC to meet the environmental protection requirements of more and more fields. The so-called elastomer refers to glass transition temperature lower than room temperature, elongation at break > 50%, external force Polymer materials with better recovery after removal. Polyurethane elastomers are a special category of elastomers. Polyurethane elastomers have a wide range of hardness and performan...
